From April 8th to May 5th, 2008, the Light-Art Object
"Rotating Elements"
by Juergen Ruedinger was to be seen at the front of the
Explora Museum in the city of Frankfurt in Germamy.

During the day the slowly rotating object can be seen. Full rotation
speed will be reached after dusk, when the pulsed uv-light sources are
at work

Description
Abstract Light-Art object with a remarkable size of 9 meters (30 feet)
in diameter, rotating at a high speed of one rotation per second. The
tip of the triangle reaches a speed of nearly 100 Kilometers per hour
(60 mph). The
surface is covered with flourescent
material. Through activation from outside by pulsed ultraviolet light,
astonishing optical effects occur. Because of the fast rotation and the
pulsed uv radiation the boundaries dissolve completely for the eyes of
the spectator, while constantly creating new forms
